Title: Integrated optical waveguide bend having an edge guide
Inventor: YOUNG TERENCE PAUL
IPC: G02B6/125
Filed: 1987-09-09
Abstract: An integrated optic device comprises a strip-like waveguide having a bend e.g. a Z-bend 10, 20 to provide a lateral offset. Weak lateral guiding in the waveguide is provided by giving the waveguide a higher effective refractive index than that of the remaining material in that layer.

Title: Biological treatment of waste water
Inventor: HATTORI TAKASHI
IPC: C02F3/10
Filed: 1991-03-12
Abstract: There is described a small-sized and low cost waste water biological treating tank especially suitable for domestic installation. The tank 10 contains a porous soft ceramic material 40 which supports the treating microorganisms. Waste or raw water is supplied to the tank from above through a downwardly opening pipe 21, is pushed up by the action of air bubbles generated by a bottom mounted air inlet 30, and then flows over a cylindrical weir 50 into the ceramic material 40 in which the water is purified by microorganisms which digest the nutrient in the water. The surface area of the porous ceramic element 40 is generally about 25 times greater than that of conventional plastics elements. Treated water passes through an outlet 12 and may then be subjected to a centrifugal sludge separation step and an anaerobic biological treatment step (fig. 5). <IMAGE>

Patent GB-2257695-A (GB)
Title: Heat treatment of bauxite
Inventor: RIJKEBOER ALBERT
IPC: C01F7/0613
Filed: 1991-07-10
Abstract: A heat treatment process for the removal of organic matter from bauxite ore containing alumina hydrate mainly in the form of gibbsite comprises the steps of preparing the bauxite ore to particles having a size of at most 8 mm, heating said particles in a roasting zone of a roasting apparatus to a temperature of a high temperature range from 400 to 600 DEG C, while a roasting gas is contacting substantially all said particles and has a water vapour pressure not exceeding 2 kPa, and holding said particles for a period of time in said roasting zone in said temperature range in contact with said roasting gas. Thereby the amount of water bound to said alumina hydrate is reduced to less than 0.5 mole per mole alumina. Substantially all the alumina hydrate is converted to alumina, which is well extractable when processed in a process for digesting bauxite ore with an aqueous alkali solution from which aluminium hydroxide is precipitated.
Patent GB-2267753-A (GB)
Title: Test for periodontitis and susceptibility thereto
Inventor: WILLIAMS DAVID MICHAEL
IPC: G01N33/569
Filed: 1992-06-12
Abstract: Periodontitis and susceptibility thereto is tested by measuring the change in morphology of a sample of polymorphonuclear leukocytes (PMNs) from the patient at a predetermined time after incubation thereof with supernatant from a virulent strain of Porphyromonas gingivalis and comparing the result with that from a sample of PMNs from a healthy patient. Since loss of polarisation corresponds to a loss of actin which is bound by phalloidin, the change can be measured by observing a decrease in fluorescence of fluorescently labelled phalloidin in the sample. In serious cases there is a complete loss of fluorescence. Phalloidin may be labelled with Fluorescein isothiocyanate or by conjugation to biotin which is bound to enzyme-labelled avidin or streptavidin. The latter label may be determined by enzyme-linked immunosorbent assay (ELISA). A kit containing a virulent strain of P. gingivalis and labelled phalloidin or components which when reacted will give rise to labelled phalloidin is also disclosed.

Title: Foam cleaning device with vacuum extraction
Inventor: BOND ROGER DOUGLAS
IPC: A47L11/30
Filed: 1992-07-17
Abstract: A cleaning device (11) consists of a vacuum shroud assembly (12) with a peripheral skirt (21) which encloses a brush assembly (13). The brush assembly (13) is operated by injecting high-pressure foam; the foam also suspends or dissolves any dislodged contaminants. The foam is then extracted from the vacuum shroud assembly, for additional treatment, via an extraction duct. The cleaning device (11) may be attached to a robotic or manipulator arm, and may include a compliance coupling (16) for coupling the device to such an arm. <IMAGE>
Patent GB-2262027-A (GB)
Title: A dishwasher with a drying cycle
Inventor: SAKATA HIROSHI
IPC: A47L15/46
Filed: 1992-12-04
Abstract: A dishwasher includes a chamber containing the dishes or the like, a heater 40 for heating the air in the chamber, a water inlet 70 provided on the upper side of the chamber, a drain pump 36 for draining the water from the chamber, an air circulation passage 69 through which the air in the chamber is circulated, a fan 58 for circulating the air in the chamber through the air circulation passage, a dehumidifying surface 62 capable of holding water provided in the air circulation passage, and a microcomputer for controlling the drain pump, the fan and the volume of the water supplied from the water inlet. In a drying cycle, the heated air is circulated through the air circulation passage. Since the air contacts the water spread over the dehumidifying surface, and is cooled down, water is condensed from the air. Therefore, when the air is reheated, evaporation of the water droplets on the dishes increases. <IMAGE>
Patent GB-2264593-A (GB)
Title: Electrical connector with fitting confirmation mechanism
Inventor: OTAKA KAZUTO
IPC: H01R13/639
Filed: 1993-02-15
Abstract: An electrical connector (A) is provided with a fitting confirmation lock lever (7) which is easily pivotally mounted on the connector to detect complete engagement of mating connector part (B). Flexible engagement plate portions (8b) are provided at both sides of a bearing portion (8) of the lock lever, and include engagement guide surface (8d) and an engagement hole (8c). Opposed support bosses (11, 11') project from the connector part (A), to engage with the engagement holes by a snap action. Alternatively, one boss engages a said hole (8c) while the other receives the end of a coiled support spring positioned within the bearing portion (8) to bias the lever (7) outwardly. The lever (7) is normally retained against the connector (A) by hooks (10a) cammed out of engagement on insertion of mating connector (B). If the latter is completely inserted and locked in place by a lever (3) having a locking projection (3b), then lock lever (7) can be returned to its initial, locked position. If insertion is incomplete, however, projections (9) on the lock lever (7) are fouled by connector (B) parts (4'), to provide a warning. Lever (7) is readily replaceable if damaged. <IMAGE>

An alternative arrangement provides that a number of different caps are provided - of different colours (20, Fig 3). The marker may be supported adjacent a plant by being provided with a spike 14 at one end of the body. In the alternative the body, or a cap - if provided - may be apertured 34 and receive a wire or cord 36 by means of which the marker may be hung on a plant or a support adjacent a plant. The marker may be clipped, clamped or otherwise attached to a plant or support. The body may be provided with a window (26, Fig 2) through which the information on a plant label (24, Figs 1 and 2) may be read. The window may allow only a selected part of the label to be displayed. <IMAGE>
